* Fix coverity defects: 147480, 147584Tobin Harding2017-10-161-2/+1
| | | | | | | | | | | | | | | | | | | | | CID 147480: Logically dead code (DEADCODE) Remove non-null check and subsequent function call. Add ASSERT to future proof the code. usage label is only jumped to before `zhp` is initialized. CID 147584: Out-of-bounds access (OVERRUN) Subtract length of current string from buffer length for `size` argument to `snprintf`. Starting address for the write is the start of the buffer + the current string length. We need to subtract this string length else risk a buffer overflow.

* Native Encryption for ZFS on LinuxTom Caputi2017-08-141-8/+274
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change incorporates three major pieces: The first change is a keystore that manages wrapping and encryption keys for encrypted datasets. These commands mostly involve manipulating the new DSL Crypto Key ZAP Objects that live in the MOS. Each encrypted dataset has its own DSL Crypto Key that is protected with a user's key. This level of indirection allows users to change their keys without re-encrypting their entire datasets. The change implements the new subcommands "zfs load-key", "zfs unload-key" and "zfs change-key" which allow the user to manage their encryption keys and settings. In addition, several new flags and properties have been added to allow dataset creation and to make mounting and unmounting more convenient. The second piece of this patch provides the ability to encrypt, decyrpt, and authenticate protected datasets. Each object set maintains a Merkel tree of Message Authentication Codes that protect the lower layers, similarly to how checksums are maintained. This part impacts the zio layer, which handles the actual encryption and generation of MACs, as well as the ARC and DMU, which need to be able to handle encrypted buffers and protected data. The last addition is the ability to do raw, encrypted sends and receives. The idea here is to send raw encrypted and compressed data and receive it exactly as is on a backup system. This means that the dataset on the receiving system is protected using the same user key that is in use on the sending side. By doing so, datasets can be efficiently backed up to an untrusted system without fear of data being compromised.

* Add libtpool (thread pools)Brian Behlendorf2017-08-092-5/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | OpenZFS provides a library called tpool which implements thread pools for user space applications. Porting this library means the zpool utility no longer needs to borrow the kernel mutex and taskq interfaces from libzpool. This code was updated to use the tpool library which behaves in a very similar fashion. Porting libtpool was relatively straight forward and minimal modifications were needed. The core changes were: * Fully convert the library to use pthreads. * Updated signal handling. * lmalloc/lfree converted to calloc/free * Implemented portable pthread_attr_clone() function. Finally, update the build system such that libzpool.so is no longer linked in to zfs(8), zpool(8), etc. All that is required is libzfs to which the zcommon soures were added (which is the way it always should have been). Removing the libzpool dependency resulted in several build issues which needed to be resolved. * Moved zfeature support to module/zcommon/zfeature_common.c * Moved ratelimiting to to module/zfs/zfs_ratelimit.c * Moved get_system_hostid() to lib/libspl/gethostid.c * Removed use of cmn_err() in zcommon source * Removed dprintf_setup() call from zpool_main.c and zfs_main.c * Removed highbit() and lowbit() * Removed unnecessary library dependencies from Makefiles * Removed fletcher-4 kstat in user space * Added sha2 support explicitly to libzfs * Added highbit64() and lowbit64() to zpool_util.c Reviewed-by: Tony Hutter <[email protected]> Signed-off-by: Brian Behlendorf <[email protected]> Closes #6442

* Add property overriding (-o|-x) to 'zfs receive'LOLi2017-05-091-26/+49
| | | | | | | | | | | | | | | | | | | | This allows users to specify "-o property=value" to override and "-x property" to exclude properties when receiving a zfs send stream. Both native and user properties can be specified. This is useful when using zfs send/receive for periodic backup/replication because it lets users change properties such as canmount, mountpoint, or compression without modifying the source.

* OpenZFS 7742 - zfs send wrong error message with invalid long optsGeorge Melikov2017-01-311-4/+33
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are two cases: 1. if an invalid flag is passed, and 2. if a valid flag is not given a parameter. In the case of (1), the flag is either short or long. For short flags, optopt contains the character of the flag. For long, it contains zero, and we can access the long flag using argv and optind. In the case of (2), if the flag is short, optopt contains the character of the flag. If the flag is long, the value in the 4th column of the long_options table, for that flag, is returned. We could case over all those values, or we could simply use argv and optind again. Note that in the case of something like `--resume`, which is also `-t`, "t" will be returned if an argument is not provided; so the error message will say `'t': argument not provided` or similar. This could be fixed by making it so long and short options don't use the same character flag, and then combining them in the switch/case statement, but I didn't think the ugliness of the code would be worth the small usability enhancement.

* Add `zfs allow` and `zfs unallow` supportBrian Behlendorf2016-06-071-1/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ZFS allows for specific permissions to be delegated to normal users with the `zfs allow` and `zfs unallow` commands. In addition, non- privileged users should be able to run all of the following commands: * zpool [list | iostat | status | get] * zfs [list | get] Historically this functionality was not available on Linux. In order to add it the secpolicy_* functions needed to be implemented and mapped to the equivalent Linux capability. Only then could the permissions on the `/dev/zfs` be relaxed and the internal ZFS permission checks used. Even with this change some limitations remain. Under Linux only the root user is allowed to modify the namespace (unless it's a private namespace). This means the mount, mountpoint, canmount, unmount, and remount delegations cannot be supported with the existing code. It may be possible to add this functionality in the future. This functionality was validated with the cli_user and delegation test cases from the ZFS Test Suite. These tests exhaustively verify each of the supported permissions which can be delegated and ensures only an authorized user can perform it. Two minor bug fixes were required for test-running.py. First, the Timer() object cannot be safely created in a `try:` block when there is an unconditional `finally` block which references it. Second, when running as a normal user also check for scripts using the both the .ksh and .sh suffixes. Finally, existing users who are simulating delegations by setting group permissions on the /dev/zfs device should revert that customization when updating to a version with this change.

* zfs_main: fix `zfs userspace` squashing unresolved entriesPavel Boldin2016-03-301-4/+7
| | | | | | | | | | | | | | The `zfs userspace` squashes all entries with unresolved numeric values into a single output entry due to the comparsion always made by the string name which is empty in case of unresolved IDs. Fix this by falling to a numerical comparison when either one of string values is not found. This then compares any numerical values after all with a name resolved.

* Cleanup linkingRichard Yao2016-03-181-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I noticed during code review of zfsonlinux/zfs#4385 that the author of a commit had peppered the various Makefile.am files with `$(TIRPC_LIBS)` when putting it into `lib/libspl/Makefile.am` should have sufficed. Upon further examination, it seems that he had copied what we do with `$(ZLIB)`. We also have a bit of that with `-ldl` too. Unfortunately, what we do is wrong, so lets fix it to set a good example for future contributors. In addition, we have multiple `-lz` and `-luuid` passed to the compiler because each `AC_CHECK_LIB` adds it to `$LIBS`. That is somewhat annoying to see, so we switch to `AC_SEARCH_LIBS` to avoid it. This is consistent with the recommendation to use `AC_SEARCH_LIBS` over `AC_CHECK_LIB` by autotools upstream: https://www.gnu.org/software/autoconf/manual/autoconf-2.66/html_node/Libraries.html In an ideal world, this would translate into improvements in ELF's `DT_NEEDED` entries, but that is not the case because of a couple of bugs in libtool. The first bug causes libtool to overlink by using static link dependencies for dynamic linking: https://wiki.mageia.org/en/Overlinking_issues_in_packaging#libtool_issues The workaround for this should be to pass `-Wl,--as-needed` in `LDFLAGS`. That leads us to the second bug, where libtool passes `LDFLAGS` after the libraries are specified and `ld` will only honor `--as-needed` on libraries specified before it: https://sigquit.wordpress.com/2011/02/16/why-asneeded-doesnt-work-as-expected-for-your-libraries-on-your-autotools-project/ There are a few possible workarounds for the second bug. One is to either patch the compiler spec file to specify `-Wl,--as-needed` or pass `-Wl,--as-needed` via `CC` like `CC='gcc -Wl,--as-needed'` so that it is specified early. Another is to patch ltmain.sh like Gentoo does: https://gitweb.gentoo.org/repo/gentoo.git/tree/eclass/ELT-patches/as-needed Without one of those workarounds, this cleanup provides no benefit in terms of `DT_NEEDED` entry generation. It should still be an improvement because it nicely simplifies the code while encouraging good habits when patching autotools scripts.

* Support parallel build trees (VPATH builds)Turbo Fredriksson2015-07-171-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Build products from an out of tree build should be written relative to the build directory. Sources should be referred to by their locations in the source directory. This is accomplished by adding the 'src' and 'obj' variables for the module Makefile.am, using relative paths to reference source files, and by setting VPATH when source files are not co-located with the Makefile. This enables the following: $ mkdir build $ cd build $ ../configure \ --with-spl=$HOME/src/git/spl/ \ --with-spl-obj=$HOME/src/git/spl/build $ make -s This change also has the advantage of resolving the following warning which is generated by modern versions of automake.

Volumes, like filesystems, are limited by the zfs_max_recordsize=1M module option. * By default the maximum record size is limited to 1M by the module option zfs_max_recordsize. This value may be safely increased up to 16M which is the largest block size supported by the on-disk format. At the moment, 1M blocks clearly offer a significant performance improvement but the benefits of going beyond this for the majority of workloads are less clear. * The illumos version of this patch increased DMU_MAX_ACCESS to 32M. This was determined not to be large enough when using 16M blocks because the zfs_make_xattrdir() function will fail (EFBIG) when assigning a TX. This was immediately observed under Linux because all newly created files must have a security xattr created and that was failing. Therefore, we've set DMU_MAX_ACCESS to 64M. * On 32-bit platforms a hard limit of 1M is set for blocks due to the limited virtual address space. We should be able to relax this one the ABD patches are merged. Ported-by: Brian Behlendorf <[email protected]> Closes #354
